"Brown Bear," Wikipedia, the free encyclopedia. The brown bear (Ursus arctos) is a large bear distributed across much of northern Eurasia and North America. Adult bears generally weigh between 300 and 680 kilograms (660 and 1,500 lb) and its largest subspecies, the Kodiak bear, rivals the polar bear as the largest member of the bear family and as the largest land-based predator.
